Definitions
- the present invention relates to a spring frame for supporting a mattress or upholstery with a plurality of profile elements surrounding a support surface and a plurality of strips spanning the support surface and each extending between two mutually opposite profile elements, the two ends of which can each be connected to a profile element by means of a connecting element, in particular on this can be determined.
- Such spring frames can be used in particular in caravans or cabins of trucks or boats.
- the connecting elements are riveted to the profile elements. This is labor intensive and increases the weight of the spring frame.
- the invention is based on the object of eliminating these disadvantages.
- the connecting elements can be inserted into the longitudinal grooves of the profile elements in a rectilinear movement from above, especially when the groove opening the longitudinal grooves point upwards in relation to the support surface and the ribs or projections of the connecting elements point downwards.
- This makes it possible to use the connection between the ribs or projections of the connecting elements and the longitudinal grooves of the profile elements as a clamping connection and/or snap-in connection to train. Fixing with rivets or screws is therefore not necessary. The weight of the spring frame can thereby be reduced.
- a simple insertion of the connecting elements from above can also be promoted in that the profile elements above the groove openings are designed without profile sections and the ribs or projections protrude freely from the connecting elements, i.e. the connecting elements are formed in the direction of the support surface below the ribs or projections without component sections are.
- one or both longitudinal grooves are arranged in the area of a longitudinal edge of the respective profile element.
- the ribs or projections of the connecting elements can be arranged in the region of an edge of the respective connecting element facing the profile element.
- the connecting elements preferably each have a receptacle, in particular a pocket, for one end of a strip designed as a female strip or support strip for spring elements arranged thereon. This ensures a secure connection between the strips and the connecting elements.
- the strips of the spring frame can each be provided with a connecting element at both ends in advance and inserted as a whole from above into the longitudinal grooves of two opposing profile elements. This enables particularly simple and therefore cost-effective assembly of the spring frame.
- At least one of the two longitudinal grooves of the profile elements has an undercut and at least a rib of the connecting elements is provided with a locking hook, which engages behind the undercut when the connecting element is installed. This results in an advantageous snap-in connection.
- At least some of the profile elements are provided with a series of recesses or lugs and the connecting elements are each reciprocally provided with a lug or a recess, the lugs being designed for positive engagement in the recesses.
- the connecting elements are fixed relative to the profile elements due to the positive engagement of the lugs in the recesses. Even without riveting, unwanted displacement of the connecting elements in the longitudinal direction of the profile elements can be prevented.
- the recesses or noses of the profile elements are provided on the profile elements according to a predetermined grid dimension. In this way, the distance between the connecting elements from one another in the longitudinal direction of the profile elements and thus also the distance between the strips accommodated by them can be specified. This also simplifies assembly and thereby reduces costs.
- the recesses or lugs of the profile elements are provided on the outer wall of a groove and the lugs or recesses of the connecting elements are provided on an associated rib or an associated projection. This is also advantageous in production.
- the profile elements are preferably made of aluminum. Other materials such as wood or plastic are also possible.
- the connecting elements are preferably made of plastic.
- two butted ends of two profile elements are connected to one another via an angle-adjustable corner element.
- the setting angle of the corner elements can preferably be determined by a counter bearing.
- the counter bearing preferably has at least two mutually offset ribs or projections, which can each be used in one of the two longitudinal grooves of the profile elements in order to connect the corner element to the two profile elements. This uses the longitudinal grooves of the profile elements to also fix the corner elements on the profile elements.
- the counter bearings also have lugs or recesses which can be inserted in a form-fitting manner into reciprocally designed recesses or lugs of the profile elements. This means that the counter bearings can also be fixed relative to the longitudinal extent of the profile elements.
- the connecting elements and the counter bearings are connected to the profile elements only via the ribs or projections and, if necessary, the noses or recesses. Rivets or screws for connecting the connecting elements or counter bearings to the profile elements are thereby avoided, which reduces costs and weight.
- the in Fig. 1 Spring frame 1 shown (only one corner area is shown) consists of four profile elements 2, each of which is connected to one another at right angles via corner elements 3 and surrounds a support surface 4. Between two opposing profile elements 2 (only one profile element is shown) a plurality of support strips 5 are arranged, each of which carries a plurality of spring elements 6 for supporting a mattress or a cushioning element. Instead of the support strips 5 with spring elements 6, spring strips could also be provided, which in turn carry a mattress or a cushioning element.
- the support strips 5 are each connected at their two ends to the associated profile element 2 via connecting elements 7, as will be described in detail below.
- the profile element 2 shown is provided with two longitudinal grooves 8 and 9, each with a groove opening 31 pointing upwards with respect to the support surface 4, the longitudinal grooves 8, 9 being vertical in relation to the support surface 4 and perpendicular to the longitudinal extent I of the profile element 2 and are offset from one another parallel to the support surface 4.
- the groove 8, which is deeper in relation to the support surface 4, is provided with an undercut 10 and has a series of recesses 11, of which only a recess can be seen.
- the recesses 11 are arranged according to a predetermined grid dimension.
- the longitudinal grooves 8, 9 are each arranged in the area of a longitudinal edge 32 of the profile element 2.
- the connecting elements 7 shown are approximately triangular in cross section. They have a rear wall 12 that is perpendicular to the support surface 4 and a lower wall 13 that runs parallel to the support surface 4. Furthermore, the connecting elements 7 are laterally delimited by two essentially triangular side walls 14. Finally, an intermediate wall 15, which also runs parallel to the support surface 4, is provided approximately in the middle of the connecting element 7, which, together with the lower wall 13 and the two side walls 14, forms a receiving pocket 16 for the end of a strip 5.
- an angle 17 pointing away from the pocket 16 is provided, on which two projections 18 pointing towards the lower wall 13 are formed in a freely cantilevered manner.
- the projections 18 are designed for positive engagement in the upper groove 9.
- a recess 19 is provided, which is defined by an upper edge 20 and a side edge 21.
- Three projections 22 are formed on the upper edge 20 and, like the projections 18, project freely towards the lower wall 13.
- the projections 22 are designed for positive engagement in the lower groove 8.
- the projections 22 have locking lugs 23, which engage behind the undercut 10 of the lower groove 8 in a locking manner.
- the connecting elements 7 have recesses 24 in the area of the upper projections 18 and in the area of the lower projections 22 are provided with recesses 25. In this way, a connecting element 7 produced as a plastic injection-molded part can be easily removed from the mold.
- the central projection 22 of the connecting elements 7 is provided with a nose 26.
- the nose 26 is designed so that it can engage in a form-fitting manner in a recess 11 of the lower longitudinal groove 8 of the profile element 2.
- the respective connecting element 7 is fixed relative to the longitudinal extent I of the profile element 2.
- the recesses 11 specify the position at which the connecting elements 7 are to be mounted.
- Fig. 4 is shown how two profile elements 2 butted together are connected to one another via an angle-adjustable corner connector 27.
- the corner connector 27 consists of two parts 27a and 27b, which are rotatably connected to one another via a hinge-like element 28.
- a counter bearing 29 is provided, which consists of two parts 29a and 29b, which are pivotally connected to one another via a film hinge 30.
- the two parts 29a and 29b of the counter bearing 29 can be connected to the two profile elements 2 in the same way as the connecting elements 7, i.e. via upper and lower projections which engage in a form-fitting manner in the upper groove 9 and the lower groove 8 of the profile elements 2.
- the lower projections can be provided with locking lugs, which can engage behind the undercut 10 of the lower groove 8.
- the lower projections can be provided with lugs, which can each engage in a form-fitting manner in a recess 11 of a profile element 2, whereby the two parts 29a and 29b of the counter bearing 29 are fixed relative to the longitudinal extent of the respective profile element 2. This also determines the setting angle of the corner element 27.
- the corner element 7 and the counter bearing 29 can each be made of plastic.

Description
Die vorliegende Erfindung betrifft einen Federrahmen zur Abstützung einer Matratze oder einer Polsterung mit mehreren eine Stützfläche umgebenden Profilelementen und mehreren die Stützfläche überspannenden, sich jeweils zwischen zwei einander gegenüberliegenden Profilelementen erstreckenden Leisten, deren beide Enden jeweils mittels eines Verbindungselements mit einem Profilelement verbindbar, insbesondere an diesem festlegbar sind.The present invention relates to a spring frame for supporting a mattress or upholstery with a plurality of profile elements surrounding a support surface and a plurality of strips spanning the support surface and each extending between two mutually opposite profile elements, the two ends of which can each be connected to a profile element by means of a connecting element, in particular on this can be determined.
Derartige Federrahmen können insbesondere in Caravans oder Kabinen von Lastkraftwagen oder Booten eingesetzt werden. Bei bekannten Federrahmen werden die Verbindungselemente mit den Profilelementen vernietet. Dies ist arbeitsaufwendig und erhöht das Gewicht des Federrahmens.Such spring frames can be used in particular in caravans or cabins of trucks or boats. In known spring frames, the connecting elements are riveted to the profile elements. This is labor intensive and increases the weight of the spring frame.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen.The invention is based on the object of eliminating these disadvantages.
Diese Aufgabe wird gelöst durch einen Federrahmen der eingangs genannten Art mit den Merkmalen des Anspruchs 1.This task is solved by a spring frame of the type mentioned with the features of
Durch die versetzte Anordnung der Längsnuten der Profilelemente nicht nur senkrecht zur Ebene der Stützfläche sondern auch senkrecht zur Längserstreckung des jeweiligen Profilelements und parallel zur Ebene der Stützfläche können die Verbindungselemente in einer geradlinigen Bewegung von oben in die Längsnuten der Profilelemente eingesetzt werden, insbesondere wenn die Nutenöffnung der Längsnuten in Bezug auf die Stützfläche jeweils nach oben und die Rippen oder Vorsprünge der Verbindungselemente nach unten weisen. Dadurch ist es möglich, die Verbindung zwischen den Rippen oder Vorsprüngen der Verbindungselemente und den Längsnuten der Profilelemente als Klemmverbindung und/oder Einrastverbindung auszubilden. Eine Festlegung durch Nieten oder Schrauben ist daher nicht notwendig. Das Gewicht des Federrahmens kann dadurch verringert werden.Due to the offset arrangement of the longitudinal grooves of the profile elements not only perpendicular to the plane of the support surface but also perpendicular to the longitudinal extent of the respective profile element and parallel to the plane of the support surface, the connecting elements can be inserted into the longitudinal grooves of the profile elements in a rectilinear movement from above, especially when the groove opening the longitudinal grooves point upwards in relation to the support surface and the ribs or projections of the connecting elements point downwards. This makes it possible to use the connection between the ribs or projections of the connecting elements and the longitudinal grooves of the profile elements as a clamping connection and/or snap-in connection to train. Fixing with rivets or screws is therefore not necessary. The weight of the spring frame can thereby be reduced.
Ein einfaches Einsetzen der Verbindungselemente von oben kann auch dadurch gefördert werden, dass die Profilelemente oberhalb der Nutenöffnungen profilabschnittsfrei ausgebildet sind und die Rippen oder Vorsprünge von den Verbindungselementen frei auskragen, dass die Verbindungselemente also in Richtung auf die Stützfläche unterhalb der Rippen oder Vorsprünge ohne Bauteilabschnitte ausgebildet sind.A simple insertion of the connecting elements from above can also be promoted in that the profile elements above the groove openings are designed without profile sections and the ribs or projections protrude freely from the connecting elements, i.e. the connecting elements are formed in the direction of the support surface below the ribs or projections without component sections are.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind eine oder beide Längsnuten im Bereich einer Längskante des jeweiligen Profilelements angeordnet. Entsprechend vorteilhaft können die Rippen oder Vorsprünge der Verbindungselemente im Bereich einer dem Profilelement zugewandten Kante des jeweiligen Verbindungselements angeordnet sein.According to a further advantageous embodiment of the invention, one or both longitudinal grooves are arranged in the area of a longitudinal edge of the respective profile element. Correspondingly advantageously, the ribs or projections of the connecting elements can be arranged in the region of an edge of the respective connecting element facing the profile element.
Die Verbindungselemente weisen bevorzugt jeweils eine Aufnahme, insbesondere Tasche, für ein Ende einer als Federleiste oder Trägerleiste für darauf angeordnete Federelemente ausgebildeten Leiste auf. Dies gewährleistet eine sichere Verbindung zwischen den Leisten und den Verbindungselementen.The connecting elements preferably each have a receptacle, in particular a pocket, for one end of a strip designed as a female strip or support strip for spring elements arranged thereon. This ensures a secure connection between the strips and the connecting elements.
Aufgrund der erfindungsgemäßen Ausgestaltung der Verbindung zwischen Profilelementen und Verbindungselementen können die Leisten des Federrahmens jeweils bereits vorab an ihren beiden Enden mit einem Verbindungselement versehen werden und als Ganzes von oben in die Längsnuten zweier einander gegenüberliegender Profilelemente eingesetzt werden. Dies ermöglicht eine besonders einfache und damit kostengünstige Montage des Federrahmens.Due to the inventive design of the connection between profile elements and connecting elements, the strips of the spring frame can each be provided with a connecting element at both ends in advance and inserted as a whole from above into the longitudinal grooves of two opposing profile elements. This enables particularly simple and therefore cost-effective assembly of the spring frame.
Nach einer Ausgestaltung der Erfindung ist jeweils mindestens eine der beiden Längsnuten der Profilelemente mit einem Hinterschnitt und jeweils mindestens eine Rippe der Verbindungselemente mit einem Rasthaken versehen, welcher bei montiertem Verbindungselement den Hinterschnitt hintergreift. Hierdurch ergibt sich eine vorteilhafte Einrastverbindung.According to one embodiment of the invention, at least one of the two longitudinal grooves of the profile elements has an undercut and at least a rib of the connecting elements is provided with a locking hook, which engages behind the undercut when the connecting element is installed. This results in an advantageous snap-in connection.
Nach einer vorteilhaften weiteren Ausgestaltung der Erfindung ist mindestens ein Teil der Profilelemente mit einer Reihe von Aussparungen oder Nasen versehen und sind die Verbindungselemente jeweils reziprok mit einer Nase oder einer Aussparung versehen, wobei die Nasen zum formschlüssigen Eingriff in die Aussparungen ausgebildet sind. Durch den formschlüssigen Eingriff der Nasen in die Aussparungen sind die Verbindungselemente relativ zu den Profilelementen festgelegt. Auch ohne Vernieten kann dadurch ein ungewolltes Verschieben der Verbindungselemente in Längsrichtung der Profilelemente verhindert werden.According to an advantageous further embodiment of the invention, at least some of the profile elements are provided with a series of recesses or lugs and the connecting elements are each reciprocally provided with a lug or a recess, the lugs being designed for positive engagement in the recesses. The connecting elements are fixed relative to the profile elements due to the positive engagement of the lugs in the recesses. Even without riveting, unwanted displacement of the connecting elements in the longitudinal direction of the profile elements can be prevented.
Nach einer vorteilhaften Weiterbildung sind die Aussparungen oder Nasen der Profilelemente gemäß einem vorgegebenen Rastermaß an den Profilelementen vorgesehen. Hierdurch kann der Abstand der Verbindungselemente voneinander in Längsrichtung der Profilelemente und damit auch der Abstand der von diesen aufgenommenen Leisten vorgegeben werden. Auch dies vereinfacht die Montage und verringert dadurch die Kosten.According to an advantageous development, the recesses or noses of the profile elements are provided on the profile elements according to a predetermined grid dimension. In this way, the distance between the connecting elements from one another in the longitudinal direction of the profile elements and thus also the distance between the strips accommodated by them can be specified. This also simplifies assembly and thereby reduces costs.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Aussparungen oder Nasen der Profilelemente an der Außenwand einer Nut und die Nasen oder Aussparungen der Verbindungselemente an einer zugeordneten Rippe oder einem zugeordneten Vorsprung vorgesehen. Dies ist in der Herstellung ebenfalls vorteilhaft.According to a further advantageous embodiment of the invention, the recesses or lugs of the profile elements are provided on the outer wall of a groove and the lugs or recesses of the connecting elements are provided on an associated rib or an associated projection. This is also advantageous in production.
Die Profilelemente bestehen bevorzugt aus Aluminium. Andere Materialien wie Holz oder Kunststoff sind ebenfalls möglich. Die Verbindungselemente bestehen bevorzugt aus Kunststoff.The profile elements are preferably made of aluminum. Other materials such as wood or plastic are also possible. The connecting elements are preferably made of plastic.
Nach einer weiteren Ausgestaltung der Erfindung sind zwei miteinander gestoßene Enden zweier Profilelemente über ein winkelverstellbares Eckelement miteinander verbunden. Hierdurch ist es möglich, Federrahmen mit unterschiedlichen Geometrien herzustellen, die auch von einer rechteckigen Geometrie abweichen können.According to a further embodiment of the invention, two butted ends of two profile elements are connected to one another via an angle-adjustable corner element. This makes it possible to produce spring frames with different geometries, which can also deviate from a rectangular geometry.
Der Einstellwinkel der Eckelemente ist bevorzugt durch ein Konterlager festlegbar. Dabei weist das Konterlager bevorzugt mindestens zwei zueinander versetzte Rippen oder Vorsprünge auf, die jeweils in einer der beiden Längsnuten der Profilelemente einsetzbar sind, um das Eckelement mit den beiden Profilelementen zu verbinden. Hiermit werden die Längsnuten der Profilelemente ausgenutzt, um auch die Eckelemente an den Profilelementen festzulegen.The setting angle of the corner elements can preferably be determined by a counter bearing. The counter bearing preferably has at least two mutually offset ribs or projections, which can each be used in one of the two longitudinal grooves of the profile elements in order to connect the corner element to the two profile elements. This uses the longitudinal grooves of the profile elements to also fix the corner elements on the profile elements.
Weiter bevorzugt weisen auch die Konterlager Nasen oder Aussparungen auf, die in reziprok ausgebildete Aussparungen oder Nasen der Profilelemente formschlüssig einsetzbar sind. Somit können auch die Konterlager relativ zur Längserstreckung der Profilelemente festgelegt werden.More preferably, the counter bearings also have lugs or recesses which can be inserted in a form-fitting manner into reciprocally designed recesses or lugs of the profile elements. This means that the counter bearings can also be fixed relative to the longitudinal extent of the profile elements.
Besonders bevorzugt sind die Verbindungselemente und die Konterlager nur über die Rippen oder Vorsprünge und gegebenenfalls die Nasen oder Aussparungen mit den Profilelementen verbunden. Nieten oder Schrauben zur Verbindung der Verbindungselemente oder Konterlager mit den Profilelementen werden dadurch vermieden, was die Kosten und das Gewicht reduziert.Particularly preferably, the connecting elements and the counter bearings are connected to the profile elements only via the ribs or projections and, if necessary, the noses or recesses. Rivets or screws for connecting the connecting elements or counter bearings to the profile elements are thereby avoided, which reduces costs and weight.
